Maven을 사용하는 Spring MVC - java.lang.ClassNotFoundException : org.springframework.web.servlet.DispatcherServlet

Question

Eclipse에서 maven을 사용하는 단순한 스프링 MVC 프로젝트를 설정하려하고 있지만 보이지 않는다. 다음과 같은 예외가 발생합니다.

이 문제에 대해 다른 사람들에게 제안 된 여러 가지 해결책이 있지만 작동하지 않는 것으로 나타났습니다.

나는 봄 - mvc가 내 pom에 있고 그것은 Maven Dependecies에있다. 나는 순간에 손실의 비트에있어

Answer 1

Spring Jars가 서버에서 런타임에 해결되지 않습니다. jar 파일을 사용할 수 있는지 확인하려면 WEB-INF/lib를 확인하십시오.

필요 :

<dependency> 
     <groupId>org.springframework</groupId> 
     <artifactId>spring-webmvc</artifactId> 
     <version>3.2.3.RELEASE</version>
